4. B modeling#
4.1. Characteristics of modeling#
Modeling AXIS_GRAD_VARI.
4.2. Characteristics of the mesh#
Number of knots: 8
Number and types of meshes: 1 QUAD8, 4 SEG3.
4.3. Tested sizes and results#
The problem considered here is homogeneous, the constraints (or the internal variables) are therefore identical at the various gauss points.
The following values are recovered at time 0.5 and 0.7: the component \({\mathrm{\sigma }}_{\mathit{yy}}\) of the stress tensor (“SIEF_ELGA”, “SIYY”), the work-hardening variable \(\mathrm{\kappa }\) (“VARI_ELGA”, “V1”) and the porosity \(f\) (“VARI_ELGA”, “V2”) and the porosity (“”, “V2”).
The following table summarizes the values obtained by the Z-set finite element calculation software.
